noun

• (An) electric shock.
  "The injection of the relaxant myocaine (glycerol ester of guaiacol) before an electroshock prevents the dysfunction of carbohydrate metabolism, restricts the splitting of phosphocreatine after cardiazol and picrotoxin, and after electroshock and amidopyrine it facilitates phosphocreatine synthesis (Mison-Crighel, 1957). Similarly, alkaline phosphatases no longer decrease after an electroshock if myocaine has previously been injected (Appel et al., 1957)."
• (medicine) Electroconvulsive therapy.
  "Although California has the toughest laws in the country regulating electroshock and requiring patient consent, due to the pressures from the medical lobby these have never been enforced. The procedure is extremely lucrative for the doctors who use it."

verb

• (medicine) To administer electroconvulsive therapy.
